Blue limestone is a timeless classic thanks to its great versatility and its technical features.

Bluestone is a compact dark limestone. The most famous are Kilkenny Limestone, from our own quarries, and Belgian Blue Stone. These materials have been used for centuries for indoor and outdoor applications. Due to its very dense structure and hardness, this limestone is ideally suited for paving, terraces, interior flooring, wall cladding and building products (window sills, lintels, stairs...).

The distinct colour of this natural stone is attributed to the remnants of ancient carbon dioxide. Bluestone typically exhibits varying shades of blue-grey, with Irish bluestone being notably bluer than its Belgian counterpart and containing fewer fossils.

Best-selling finishes

The finishes below are a selection of the most popular finishes available for bluestone. At Brachot, we are also constantly developing new finishes and optimising existing ones. So we always find the finish that best suits the material, your taste and the style of the house.

Diamond-sawn

This finish highlights the natural unrefined appearance that results from diamond frame-sawing. Light-grey in colour, the saw-marks remain clearly visible on the face. Often well-utilized on limestone for cladding and kerbing, this ready-rough finish is suitable for a multitude of uses.

Blue Honed

The smooth and even appearance rendered by the blue honed finish is achieved through the use of a range of grits. When a honed finish is applied to Irish blue limestone, the coarseness of the grit used will directly impact the colour of the final finish. The coarsest grit (100) achieves a pale blue-grey colour and produces a smooth and matt texture with a faint pattern of circular scores. Honed finishes are suitable for interiors such as worktops, flooring and cladding but are also used externally for furniture, window sills and plinths.

Flamed

Flamed faces have a slightly translucent speckled grey colour, varied by slightly and randomly developed lighter areas. The surface is smooth but with an irregular texture of minor creases. This finish is the result of the torching of the stone surface with a white hot open flame, lending a modern finish with a truly original texture. With excellent slip-resistant properties, flamed Irish limestone is perfect for outdoor uses, including paving and landscaping works, paths and terraces. The distinctive aesthetic of this finish has also made it popular for cladding and indoor use.

Bush Hammered

The bush hammered finish delivers a dark blue-grey background with randomly distributed, closely spaced and contrasting paler blue-grey indentations. The surface has a smooth background which is in contrast to a pattern of fine dimpling. Due to its superior slip-resistant qualities, Irish blue limestone with a bush hammered finish is an ideal choice for outdoor use on paving, kerbs and steps. This finish is also applied for decorative purposes and to showcase the various characteristics in a large piece of Irish blue limestone.

Line chiselled

This classic masonry technique involves incising the limestone surface with a series of parallel thin lines. These rows of incisions in the limestone appear dark grey or black set against the smooth curved surfaces of the stone. The chiselled finish achieves a paler blue-grey colour with the ancient crinoids revealing themselves as a randomly distributed pattern of paler grey flecks. Chiselled blue limestone is an excellent finish for both internal and external applications such as cladding, ashlar, lintels, mouldings, pavilions, setts, kerbs and steps.
